More castles than you could wish for - e.g Carlisle Castle - present castle was started by King David 1st of Scotland and completed by King William 2nd Rufus of England in 1083. Used to house Mary Queen of Scots whilst Elizabeth1st decided what to do with her.
Carlisle Cathedral has the 3rd biggest East window in the world, the cathedral was partly demolished to rebuild the City walls to keep out rampaging Scotsmen in 1745/6, when Carlisle changed hands between Scottish and English forces and back several times. Now the cathedral looks really odd because a great part of it was not rebuilt.
